CLAMP. APPLICATION FILED MAR.16, 190Gx A TTORNE Y5 Jo o/,1 whom; it Wm,concern) "iiir isemeeop i the United States, residing at Littlestdwiifin thec'ounty of Adams and State of Pennsylvania, have i-nvented'anew and'use "i'ul Clampmfwhiclfthe following is a 'specification! '1 w 1This invention relates to devices employed ticularly'ferclampingtwowires.

The device'ina'y be employed for clamping for elamping' twobodiestogether, morepartogether'the ends of two wires, for clamping two vwiresintermediate the ends, 'for "coup 'li'n'g two wires'in 'tran-s-verserelations, and? the .likeZ-C' i 1 P 1 i r The devide may be employed forconnectiiig teleg'raph, -telephone, or similar wires .in

.In the arrangement shown in'Fig; lith wire 18 at one'end oftheclamping-plates and the wire 18 is coiled at 22 around ,th' wire 19at-the opposite end'of the'clampin plates, the wire 18 being continuedlaterall yj to from the .guy-wire 20. This arrangement may also he emloyed when itjs desire'dtofi ioo connect a hranc 1 wire in telegraphandtele;

p'hone structures for any requir d purpose.

couple two wires either at their ad'acentends 05- or intermediate thesame, as will e obvious.

In Figs.- 3,- 4, 5, and 9 there is shown the clamping device arrangedfor supporting stranthwiresupon fence-posts, and n this arrangement theends of theiouter plate are of r m greater'length than the inner'plateand di verge, as at 23 24, for hearing against the W guy-wi s 1 i andwith a bridging-wireill cou ling a pair post represented at 25. In thearrangement shown in Figs. 3, 4, and 5'one wire only will be requiredfor the plates, (represented at 26,) this single wire being attached atthe ends to the iost 25 and extending through a plurality oi the pairsof clamping-plates, there being as many ofthe pairs of clam ingplates asthere are stramhwires27, the utter passing through transverse aperturesin the plates, preferably between the clamping. iolts 28, as shown. Bythis simple "means the strand-wires are firmly supported in positionrelative to the post.

in Fig. lithe-manner of employing the improved claniping device forsuspending a cable irom -a stay-wire is shown, the staywire beingrepresented at 29, the cable at 30,

of the clamping-p ates disposer ypon the stay-wire with a )air of theclamping-plates disposed upon t e cable, the latter necessarily largerthan the clamping-plates upon the stay-wire to correspond tothegincreasing sire of the cable.

lin Figs. 7 andS the device is shown provided with three oi; theclamping-bolts, which arrangement, will be employed where it is desiredto'eou ple the wires with greater firmness or where the wires aresubjected to abnormal strains.

The device is simple in construction, can i he inexpensivelymanufactured, readily a'pplied, and will hold the wires against all'(llfiplacements so long as-the holding means 128 are not entirelydetached.

lit will be obvious by this anangemtmt l that when'bolts are employed asthe securing means :the binding-nuts may he loosened or l almostentirely removed without danger of l the displacement of the wire, asthd'plates cannot be separated solong as the bolts are in amsitienthrough the plates. 3 n :Fig. it) another form ol'post is shown combinedwith theinrproved clamping devices, the post'bc'mg cmistrueted from anelongated, U-shaped rod '32 of suflicient strength, with the spaced endsinserted into the ground or into a suitable supporting-base and with theclamping devices embracing the spaced sides of the rod with a centralaper: turc to receive the strand-wire 27. PM clamping devices aresubstantially the same as shown in Figs. 7 and 8, except that they arelarger and wider, as the U-shaped rod 32 is of larger gage and with thesides spaced farther apart, but otherwise the constructhm issubstantially the same.

Havin thus described the invention, wha't iselaiincr is l. A device ofthe character described comprising an inner and an outer plate, saidplates being oppositely disposed and the inner plate having its endportions op iositely bowed and fitting snugly within the hendof theouter plate, and clamping means extending through the inner and outerplates between their bends and terminals.

2. A device of the character described comprising an inner and an outerplate, said lates being oppositely disposed and each iblded at thecenter, the inner plate having its terminals bowed in oppositedirections to constitute clanrping-jaws fitting snugly within the bendof the outer date, said plates having alining apertures therein betweentheir bends and terminals, and a clamping device extending through theapertures.

3. A device of the charlwtcr described 1 comprising a folded springinner clampingplate, a folded spring outer clam iing-plate, and meansextending through Hltit plates for contracting them.

in testimony that I claim the foregoing as my own I have hereto a'llixedmy signature in the presence oi two witnesses. 1
